Selected Geomagnetic Measurements From Several Satellites

More than 17 million selected magnetic observations from several orbiting low-altitude
satellites are contained in this digital collection. Except for MAGSAT, all the observations
are of total intensity (F) only. The MAGSAT data contain both scalar and vector X,
Y, Z) values. MAGSAT was launched into a sun-lit, sun- synchronous orbit (350 to 550
km high) on October 30, 1979 with re- entry occurring on June 11, 1980. The MAGSAT
data are being used for derivation of magnetic field models, magnetic field mapping,
magnetic anomaly mapping, and inner earth studies. Twelve 9-track 1600 BPI, binary
magnetic tapes {INV-B} cover a time span from November 2, 1979 to May 19, 1980. The
data are organized by orbit number. Each data record contains 30 data points at approximately
5 second intervals. Additional magnetic tapes contain MAGSAT low- latitude scalar
anomaly value data, gridded scalar anomaly data and Quiet Time data. In addition to
the MAGSAT data, data from the OGO, Cosmos and Vanguard satellites are available.
The POGS experiment magnetometer is of the same type that was designed and built by
NASA for the Defense Meteorological Satellite Program (DMSP). The only modification
to the design was to add extra thermal mass in order to reduce the magetometer's thermal
drift to something less than 50 mT/goev. The U.S. Navy uses this satellite to update
its World Magnetic Model (WMMxx). Inclination Apogee Perigee Launch Dates: OGO2 10-14-65

While every effort has been made to ensure that these data are accurate and reliable
within the limits of the current state of the art, NOAA cannot assume liability for
any damages caused by any errors or omissions in the data, nor as a result of the
failure of the data to function on a particular system. NOAA makes no warranty, expressed
or implied, nor does the fact of distribution constitute such a warranty.

2015-04-22T00:00:00 - NOAA created the National Centers for Environmental Information (NCEI) by merging
NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC),
and National Oceanographic Data Center (NODC), including the National Coastal Data
Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations
Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
